Stellafane 2008 - Al-Paslow
This instrument features the "Porter" or "Springfield" Mount. This is essentially a telescope that moves about the eyepiece which is stationary.  The advantages  are clear for people who have limited access to  the telescope.  You can remain in a wheel chair and observe  from what is basically part of a declination shaft!!
